net: cpsw: do not register cpts twice

commit f280e89a (drivers: net: cpsw: fix for cpsw crash when build as modules)
moved cpts_register()/cpts_unregister() to  ndo_open()/ndo_stop(), but failed
to remove cpts_register in cpsw_probe() which leads to a double registration
and the following debug object splat.
